An organic light-emitting
diode display device includes a data line, a first and second gate lines crossing the data line, an emission line crossing the data line, an organic light-emitting
diode device having an
anode electrode and a
cathode electrode, a high-level potential driving
voltage source for supplying a high-level potential driving
voltage to the
anode electrode, a first switch element for connecting a
cathode electrode of the organic light-emitting
diode device to a first node, a second switch element for connecting the data line to a second node, a third switch element for connecting the second node to a ground
voltage source, a driving element for adjusting a current flowing between the
cathode electrode of the organic light-emitting diode device and the first node in accordance with a voltage of the first node, a first
capacitor connected between the second gate line and the first node, and a second
capacitor connected between the first node and the second node.
